Sunset Key Beach: Private Island Paradise Near Key West (2026)

Just 500 yards off the bustle of Key West, across a short stretch of harbor, sits a 27-acre private island with white-sand beaches, swaying palms, and a hush you won’t find anywhere in Old Town. This is Sunset Key — an “island off an island” — and its powdery beach is the most exclusive, postcard-perfect patch of sand in the Key West area. It’s not a public beach, but there are a few ways to experience it, and for a honeymoon, anniversary, or once-in-a-lifetime splurge, it’s pure paradise. Here’s my complete guide to Sunset Key beach and how to set foot on it.

What is Sunset Key?

Sunset Key is a manmade, 27-acre private island just off the western tip of Key West, developed into one of Florida’s most exclusive escapes. It’s home to Sunset Key Cottages, a luxury resort of only about 40 one- to four-bedroom cottages, along with a private white-sand beach, a lagoon-style swimming pool, a spa, and tennis courts. There are no cars, no crowds, and no Duval Street noise — just a serene, palm-shaded island where the loudest sound is the lapping water. Locals call it the “island off an island,” and stepping off the ferry feels like crossing into a different, gentler world, all while Key West’s skyline sits just across the water. It’s the kind of place that anchors a special-occasion trip; for the broader luxury picture, see our Key West luxury resorts guide.

The beach itself

Here’s the thing that makes Sunset Key special: its beach is among the few genuinely soft, white-sand beaches in the immediate Key West area, a cut above the island’s modest, often-rocky public beaches. Backed by palms and looking out over calm, clear water, it’s the tropical-beach fantasy that mainland Key West can’t quite deliver. Because access is limited to resort guests and diners, it’s also blissfully uncrowded — you won’t be fighting for space or dodging vendors. Loungers, gentle water, and total tranquility make it perfect for a slow day of doing absolutely nothing. For how it compares to the island’s other sands, our Key West beaches guide has the full rundown, and our beachfront hotels guide covers other waterfront stays.

How to get to Sunset Key (the access rules)

This is the crucial part: Sunset Key is private, so you can’t just hop the ferry for a beach day. There are three ways to gain access, all via the guest ferry that departs from the Sunset Key Guest Ferry Terminal at the Margaritaville Resort Marina (245 Front Street) for the scenic 10-minute ride:

• Stay at Sunset Key Cottages. Resort guests have full run of the island and its beach — the only way to truly experience it at leisure.
• Dine at Latitudes. A confirmed reservation (lunch, happy hour, or dinner) at the island’s acclaimed Latitudes restaurant gets you on the ferry.
• Book the spa. A confirmed appointment at the Sunset Key Spa also grants ferry access.

For most non-guests, a meal at Latitudes is the realistic way to set foot on Sunset Key — and it happens to be one of the most romantic dining experiences in the Keys.

Latitudes: the way most people visit

If you’re not staying overnight, Latitudes is your golden ticket. This beachfront restaurant — repeatedly ranked among the most romantic in America — serves refined coastal cuisine right on the sand, with an unobstructed western horizon that makes it one of the premier sunset spots anywhere. Book a sunset dinner and you’ll get the ferry ride, a stroll on the beach, and a magical meal as the sky lights up. Reservations are essential and book up well in advance, especially for sunset seatings in peak season, so plan ahead. It’s a splurge, but as a way to experience this exclusive island without the resort price tag, it’s worth every penny — our Key West fine dining guide and waterfront restaurants guide have more on it.

Staying at Sunset Key Cottages

If you want the full Sunset Key experience, staying overnight is the way to do it. Sunset Key Cottages is an intimate resort of only around 40 cottages, ranging from one to four bedrooms, scattered along the beach and among the palms. The cottages have a residential, beach-house feel — think wraparound porches, full kitchens in many units, and a private, home-away-from-home atmosphere rather than a generic hotel block. Guests enjoy unlimited run of the island: the private white-sand beach, a large lagoon-style swimming pool, the Sunset Key Spa, tennis courts, and a daily continental breakfast, with the ferry running back and forth to Key West so you can dip into the action and retreat to your private island whenever you like. Because the resort is so small and exclusive, it books up far in advance for peak season and holidays, so plan early. For other high-end stays on the main island, our luxury resorts guide and beachfront hotels guide have more.

A perfect day (or evening) on Sunset Key

However you access the island, here’s how to savor it. If you’re a resort guest, start with the included breakfast, then claim a lounger on the quiet beach for a morning of swimming and reading, broken up by a dip in the lagoon pool and maybe a spa treatment. Take the ferry over to Key West in the afternoon for sightseeing or shopping, then return to the island’s calm for the evening. If you’re visiting via Latitudes, book a late-afternoon or sunset reservation, arrive with time to walk the beach beforehand, and settle in for dinner as the sun sinks into the Gulf — the west-facing setting makes it one of the best sunset meals anywhere. Either way, the magic of Sunset Key is the contrast: total tranquility and a pristine beach, with the energy of Key West just a 10-minute boat ride away whenever you want it.

How Sunset Key compares

It’s worth understanding where Sunset Key fits among Key West’s options. Compared with the island’s public beaches (Smathers, Higgs, Fort Zachary Taylor), Sunset Key offers far softer sand, calmer water, and no crowds — but at a steep price and with no public access. Compared with the island’s other luxury resorts, its private-island setting and exclusivity are unmatched; nowhere else gives you that “island off an island” seclusion. And compared with a day trip to Bahia Honda or the Dry Tortugas, Sunset Key is far closer and more polished, though those parks offer a wilder, more affordable natural-beach experience. In short, Sunset Key is the choice when privacy, romance, and pampering matter more than budget or buzz. Weigh it against the alternatives in our beaches guide and beaches near Key West guide.

A bit of Sunset Key history

Sunset Key wasn’t always a luxury escape. The 27-acre island is manmade, originally known as Tank Island — created from material dredged out of the harbor and later used by the U.S. Navy to store fuel. For decades it was an industrial outpost, not a paradise. In the 1990s it was redeveloped into the upscale residential and resort island it is today, with private homes and the cottages resort, its industrial past completely transformed into palms and white sand. It’s a fittingly Key West story — a quirky, against-the-odds reinvention — and a reminder that even the island’s most polished corners have colorful histories. You can dig into more of the area’s surprising past in our Key West history and culture guide.

Who Sunset Key is perfect for

Sunset Key isn’t for everyone, and that’s the point. It’s ideal for travelers seeking luxury, privacy, and romance — honeymooners, couples celebrating an anniversary, or anyone wanting a serene, splurgy escape from the crowds. Families with the budget will find it idyllic too, with the safe, calm beach and lagoon pool. If you’re after Key West’s lively, affordable, anything-goes side, this isn’t it — but if you want one extraordinary, peaceful day or stay in paradise, few places anywhere compare. Couples planning a romantic trip should pair this with our romantic Key West guide, and those wanting a child-free atmosphere can explore our adults-only guide.

What it costs and what to expect

Set expectations on price: Sunset Key is a luxury experience at luxury prices. Cottage stays run well into the high hundreds or thousands per night depending on season and size, and a dinner for two at Latitudes with wine is a genuine splurge. What you get in return is exclusivity, impeccable service, and a private-island setting you simply can’t find elsewhere near Key West. Don’t expect a budget beach day — there’s no public access and no cheap way on. But for a milestone celebration, the value is in the once-in-a-lifetime feeling. If the budget doesn’t stretch to a stay, the Latitudes meal delivers the experience at a fraction of the overnight cost. For ways to balance a splurge against the rest of your trip, see our budget guide.

Tips for visiting Sunset Key

• Book Latitudes well ahead for a sunset reservation — it’s the most popular and the most magical, and it sells out.
• Arrive early for your ferry at the Margaritaville Marina (245 Front Street); confirm the schedule when you book.
• Allow time to enjoy the beach before or after your meal or spa appointment.
• Dress resort-casual — elegant but relaxed, as with all Key West dining.
• Consider a special-occasion stay if the budget allows; the overnight experience is unmatched.
• Time it for sunset — the island’s west-facing beach is named for exactly that reason.

Practical tips and what to bring

A few practical notes make a Sunset Key visit smoother. Because there are no cars on the island, you travel on foot once you arrive, and resort guests get around by walking or using the property’s amenities — pack light and wear comfortable sandals. Bring reef-safe sunscreen, a hat, and sunglasses; the beach has shade but the sun is strong. If you’re a day visitor coming for Latitudes, remember the ferry runs on a schedule, so build in buffer time on both ends and confirm the last return boat so you don’t get stranded (a good problem, perhaps, but plan anyway). Dress resort-casual for dining — elegant but breezy. If you’re staying over, note that while many cottages have kitchens, you’ll likely want at least one meal at Latitudes, and the ferry makes it easy to dine in Old Town too. Finally, book everything well ahead — the cottages, sunset dinner reservations, and spa appointments all fill quickly in high season, and they are the only ways onto the island. A little planning is the difference between admiring Sunset Key from the Key West waterfront and actually setting foot on its sand.

However you experience it, Sunset Key delivers something genuinely rare so close to a busy tourist town: silence, space, and a beach that looks like a screensaver. Whether it’s a sunset dinner for two or a multi-night cottage stay, it’s the kind of place that turns a Key West trip into a once-in-a-lifetime memory.
